http://dx.doi.org/10.5007/1808-1711.2012v16n1p1 A teoria darwinista tem contribuído para a discussão de problemas nos mais diversos campos filosóficos, entre os quais se inclui a ética e a teoria moral. A sociobiologia e a psicologia evolucionista elucidaram muitos aspectos do comportamento social de diversas espécies animais, a partir de mecanismos como a seleção de parentesco e o altruísmo recíproco que, contudo, são insuficientes para explicar a cooperação no caso humano. Como alternativa, a teoria da dupla herança busca explicar o comportamento humano considerando tanto (...) a biologia quanto as ciências sociais. Segundo esta abordagem, a psicologia social humana é caracterizada por instintos sociais tribais e marcadores simbólicos, que resultam em uma mente que pressupõe princípios morais inatos e universais, selecionados para a vida em grupos orientados por normas sociais, mas que são plasticamente moldados à realidade cultural de cada sociedade.

The Linda paradox is a key topic in current debates on the rationality of human reasoning and its limitations. We present a novel analysis of this paradox, based on the notion of verisimilitude as studied in the philosophy of science. The comparison with an alternative analysis based on probabilistic confirmation suggests how to overcome some problems of our account by introducing an adequately defined notion of verisimilitudinarian confirmation.

Formal methods developed for modeling levels of selection problems have recently been applied to the investigation of major evolutionary transitions. We discuss two new tools of this kind. First, the ‘near-variant test’ can be used to compare the causal adequacy of predictively equivalent representations. Second, ‘state-variable gestalt-switching’ can be used to gain a useful dual perspective on evolutionary processes that involve both higher and lower level populations.

We offer an account of empathetic pain that preserves the distinctions among standard pain, contagious pain, empathetic pain, sympathy for pain, and standard pain ascription. Vicarious experiences of both contagious and empathetic pain resemble to some extent experiences of standard pain. But there are also crucial dissimilarities. As neuroscientific results show, standard pain involves a sensorimotor and an affective component. According to our account, contagious pain consists in imagining the former, whereas empathetic pain consists in imagining the latter. We further (...) argue that awareness of another's standard pain is part of empathetic pain, but empathetic awareness of another's standard pain differs from believing that another is in standard pain.

This article argues that various deviations from the basic principles of the scientific ethos – primarily the appearance of pseudoscience in scientific communities – can be formulated and explained using specific models of game theory, such as the prisoner’s dilemma and the iterated prisoner’s dilemma. The article indirectly tackles the deontology of scientific work as well, in which it is assumed that there is no room for moral skepticism, let alone moral anti-realism, in the ethics of scientific communities. Namely, on (...) the basis of the generally accepted dictum of scientific endeavor as the pursuit of knowledge exclusively for knowledge’s sake, scientifically »right« behavior is seen to be clearly defined and distinguishable from scientifically »wrong« behavior. After elucidating the basic principles of game theory, the article illustrates – by using imaginary and real cases, as well as some views from the philosophyof biology (the units of selection debate) – how this sort of reasoning could be applied in an analysis of the functioning of science.

It’s recently been argued that biological fitness can’t change over the course of an organism’s life as a result of organisms’ behaviors. However, some characterizations of biological function and biological altruism tacitly or explicitly assume that an effect of a trait can change an organism’s fitness. In the first part of the paper, I explain that the core idea of changing fitness can be understood in terms of conditional probabilities defined over sequences of events in an organism’s life. The result (...) is a notion of “conditional fitness” which is static but which captures intuitions about apparent behavioral effects on fitness. The second part of the paper investigates the possibility of providing a systematic foundation for conditional fitness in terms of spaces of sequences of states of an organism and its environment. I argue that the resulting “organism–environment history conception” helps unify diverse biological perspectives, and may provide part of a metaphysics of natural selection. (shrink)

Industrial melanism, according to the traditional explanation, amounts to niche construction since it involves changes in predation pressure. Indeed, it would be difficult to imagine selection without niche construction. This cannot be what Laland, Odling-Smee & Feldman mean. They offer convincing examples, but they should provide a better definition of “niche construction” to indicate how their view supplements traditional evolutionary biology.

Shame is a painful emotion concerned with failure to live up to certain standards, norms, or ideals. The subject feels that she falls in the regard of others; she feels watched and exposed. As a result, she feels bad about the person that she is. The most popular view of shame is that someone only feels ashamed if she fails to live up to standards, norms, or ideals that she, herself, accepts. In this paper, I provide support for a different (...) view, according to which shame is about failure to live up to public expectations. Such a view of shame has difficulties explaining why an audience is central to shame, why shame concerns the self as a whole, and why the social rank of someone affects their ability to shame others. These features, I argue, are best explained by reference to the descent of shame in the emotion connected with submission in nonhuman animals. The function of submission—to appease relevant social others—also throws light on the sort of emotion that shame is. From the point of view of other people, a subject who experiences shame at her own failing is someone who is committed to living together with others in a socially sanctioned way. The argument is not that we must understand the nature of shame in terms of what it evolved for, but that its heritage is important to understanding the emotion that shame has become. (shrink)

Sober and Wilson have recently claimed that evolutionary theory can do what neither philosophy nor experimental psychology have been able to, namely, "break the deadlock" in the egoism vs. altruism debate with an argument based on the reliability of altruistic motivation. I analyze both their reliability argument and the experimental evidence of social psychology in favor of altruism in terms of the folk-psychological "laws" and inference patterns underlying them, and conclude that they both rely on the same patterns. I expose (...) the confusions that have led Sober and Wilson to defend a reliability argument while rejecting the experimental evidence of social psychology. (shrink)

According to the received view of evolution, only genes are inherited. From this view it follows that only genetically-caused phenotypic variation is selectable and, thereby, that all selection is at bottom genetic selection. This paper argues that the received view is wrong. In many species, there are intergenerationally-stable phenotypic differences due to environmental differences. Natural selection can act on these nongenetically-caused phenotypic differences in the same way it acts on genetically-caused phenotypic differences. Some selection is at bottom nongenetic selection. The (...) argument against the received view involves a reformulation of the concepts of inheritance and heritability. Inherited factors are all those developmental factors responsible for parent–offspring similarity; some inherited factors are genetic and some are not. Heritable variation is intergenerationally-stable phenotypic variation; some such variation is genetically-caused and some is not.

The problem of moral compliance is the problem of explaining how moral norms are sustained over extented stretches of time despite the existence of selfish evolutionary incentives that favor their violation. There are, broadly speaking, two kinds of solutions that have been offered to the problem of moral compliance, the reciprocity-based account and the punishment-based account. In this paper, I argue that though the reciprocity-based account has been widely endorsed by evolutionary theorists, the account is in fact deeply implausible. I (...) provide three arguments that suggest that moral norms are sustained by punishment, not reciprocity. But in addition to solving the problem of moral compliance, the punishment-based account provides an additional important theoretical dividend. It points the way for how theorists might build an evolutionary account of a feature of human groups that has long fascinated and troubled social scientists and moral philosophers – the existence of moral diversity.

Hybrid accounts of folk psychology maintain that we sometimes theorize and sometimes simulate in order to understand others. An important question is why this is the case. In this paper, I present a view according to which simulation, but not theory, plays a central role in empathy. In contrast to others taking a similar approach to simulation, I do not focus on empathy’s cognitive aspect, but stress its affective-motivational one. Simulating others’ emotions usually engages our motivations altruistically. By vicariously feeling (...) what others are feeling, we directly come to be motivated by their projects and concerns. Simulation contrasts with more theoretical approaches to psychological attribution that help us understand and explan others, but that do not move us altruistically. This helps us see why we would posit two different folk psychological approaches instead of merely one. (shrink)

Several prominent debates in biology, such as those surrounding adaptationism, group selection, and punctuated equilibrium, have focused on disagreements about the relative importance of a cause in producing a phenomenon of interest. Some philosophers, such as John Beatty have expressed scepticism about the scientific value of engaging in these controversies, and Karen Kovaka has suggested that their value might be limited. In this paper, I challenge that scepticism by giving a novel analysis of relative significance controversies, showing that there are (...) three forms they can take. I argue that these controversies can have significant epistemic upshots, in that they help scientists form predictions about new instances of the phenomenon of interest. Finally, using two historical examples, I show how engaging in these controversies can improve our understanding of causal relationships. (shrink)

Molecular methods have revolutionised virtually every area of biology, and metazoan phylogenetics is no exception: molecular phylogenies, molecular clocks, comparative phylogenomics, and developmental genetics have generated a plethora of molecular data spanning numerous taxa and collectively transformed our understanding of the evolutionary history of animals, often corroborating but at times opposing results of more traditional approaches. Moreover, the diversity of methods and models within molecular phylogenetics has resulted in significant disagreement among molecular phylogenies as well as between these and earlier (...) phylogenies. How should this broad and multifaceted problem be tackled? I argue that the answer lies in integrating evidence to infer the best evolutionary scenario. I begin with an overview of recent development in early metazoan phylogenetics, followed by a discussion of key conceptual issues in phylogenetics revolving around phylogenetic evidence, theory, methodology, and interrelations thereof. I then argue that the integration of different kinds of evidence is necessary for arriving at the best evolutionary scenario rather than merely the best-fitting cladogram. Finally, I discuss the prospects of this view in stimulating interdisciplinary cross-talk in early metazoan research and beyond, and challenges that need to be overcome. (shrink)

The dominant theory of the evolution of moral cognition across a variety of fields is that moral cognition is a biological adaptation to foster social cooperation. This chapter argues, to the contrary, that moral cognition is likely an evolutionary exaptation: a form of cognition where neurobiological capacities selected for in our evolutionary history for a variety of different reasons—many unrelated to social cooperation—were put to a new, prosocial use after the fact through individual rationality, learning, and the development and transmission (...) of social norms. This chapter begins with a brief overview of the emerging behavioral neuroscience of moral cognition. It then outlines a novel theory of moral cognition that I have previously argued explains these findings better than alternatives. Finally, it shows how the evidence for this theory of moral cognition and human evolutionary history together suggest that moral cognition is likely not a biological adaptation. Instead, like reading sheet music or riding a bicycle, moral cognition is something that individuals learn to do—in this case, in response to sociocultural norms created in our ancestral history and passed down through the ages to enable cooperative living.

Affective empathy has been variously characterized. First, I argue that we have reasons to prefer a narrower account of affective empathy, which requires the cognitive mechanisms of perspective-taking. Second, I mount a challenge to the standard account of affective matching thought to be required for affective empathy. On one widely held view, affective empathy requires an actual affective match between the subject and the target of empathy. I reject this view. While empathy often involves an actual match, we also count (...) as empathizing with the target if we share the fitting state in their situation. This wider account better captures a number of plausible cases of empathy, and it also better explains why we care about affective empathy. (shrink)

In Regard for Reason in the Moral Mind, Joshua May argues successfully that many claims about the causal influence of affect on moral judgment are overblown. But the findings he cites are compatible with many of the key arguments of philosophical sentimentalists. His account of rationalism, in turn, relies on an overly broad notion of inference, and leaves open crucial questions about how we reason to moral conclusions.

Egoism and altruism are unequal contenders in the explanation of human behaviour. While egoism tends to be viewed as natural and unproblematic, altruism has always been treated with suspicion, and it has often been argued that apparent cases of altruistic behaviour might really just be some special form of egoism. The reason for this is that egoism fits into our usual theoretical views of human behaviour in a way that altruism does not. This is true on the biological level, where (...) an evolutionary account seems to favour egoism, as well as on the psychological level, where an account of self-interested motivation is deeply rooted in folk psychology and in the economic model of human behaviour. While altruism has started to receive increasing support in both biological and psychological debates over the last decades, this paper focuses on yet another level, where egoism is still widely taken for granted.Philosophical egoism is the view that, on the ultimate level of intentional explanation, all action is motivated by one of the agent's desires. This view is supported by the standard notion that for a complex of behaviour to be an action, there has to be a way to account for that behaviour in terms of the agent's own pro-attitudes.Psychologicalaltruists, it is claimed, arephilosophicalegoists in that they are motivated by desires that have the other's benefit rather than the agent's own for its ultimate object. This paper casts doubt on this thesis, arguing that empathetic agents act on other people's pro-attitudes in very much the same way as agents usually act on their own, and that while other-directed desires do play an important role in many cases of psychologically altruistic action, they are not necessary in explanations of some of the most basic and most pervasive types of human altruistic behaviour. The paper concludes with the claim that philosophical egoism is really a cultural value rather than a conceptual feature of action. (shrink)

In recent attempts to characterize the cognitive mechanisms underlying altruistic motivation, one central question is the extent to which the capacity for altruism depends on the capacity for understanding other minds, or ‘mindreading’. Some theorists maintain that the capacity for altruism is independent of any capacity for mindreading; others maintain that the capacity for altruism depends on fairly sophisticated mindreading skills. I argue that none of the prevailing accounts is adequate. Rather, I argue that altruistic motivation depends on a basic (...) affective system, a ‘Concern Mechanism’, which requires only a minimal capacity for mindreading. (shrink)

There are three questions associated with Simpson’s Paradox (SP): (i) Why is SP paradoxical? (ii) What conditions generate SP?, and (iii) What should be done about SP? By developing a logic-based account of SP, it is argued that (i) and (ii) must be divorced from (iii). This account shows that (i) and (ii) have nothing to do with causality, which plays a role only in addressing (iii). A counterexample is also presented against the causal account. Finally, the causal and logic-based (...) approaches are compared by means of an experiment to show that SP is not basically causal. (shrink)

Do multi-level selection explanations of the evolution of social traits deepen the understanding provided by single-level explanations? Central to the former is a mathematical theorem, the multi-level Price decomposition. I build a framework through which to understand the explanatory role of such non-empirical decompositions in scientific practice. Applying this general framework to the present case places two tasks on the agenda. The first task is to distinguish the various ways of suppressing within-collective variation in fitness, and moreover to evaluate their (...) biological interest. I distinguish four such ways: increasing retaliatory capacity, homogenising assortment, and collapsing either fitness structure or character distribution to a mean value. The second task is to discover whether the third term of the Price decomposition measures the effect of any of these hypothetical interventions. On this basis I argue that the multi-level Price decomposition has explanatory value primarily when the sharing-out of collective resources is `subtractable'. Thus its value is more circumscribed than its champions Sober and Wilson (1998) suppose. (shrink)

Understanding cooperative human behaviour depends on insights into the biological basis of human altruism, as well as into socio-cultural development. In terms of evolutionary theory, kinship and reciprocity are well established as underlying cooperativeness. Reasons will be given suggesting an additional source, the capability of a cognition-based empathy that may have evolved as a by-product of strategic thought. An assessment of the range, the intrinsic limitations, and the conditions for activation of human cooperativeness would profit from a systems approach combining (...) biological and socio-cultural aspects. However, this is not yet the prevailing attitude among contemporary social and biological scientists who often hold prejudiced views of each other's notions. It is therefore worth noticing that the desirable integration of aspects has already been attempted, in remarkable and encouraging ways, in the history of thought on human nature. I will exemplify this with the ideas of the fourteenth century Arab-Muslim historian Ibn Khaldun. He set out to explicate human cooperativeness - "asabiyah" - as having a biological basis in common descent, but being extendable far beyond within social systems, though in a relatively unstable and attenuated fashion. He combined psychological and material factors in a dynamical theory of the rise and decline of political rulership, and related general social phenomena to basic features of human behaviour influenced by kinship, expectation of reciprocity, and empathic emotions. -/- .

In this paper, my aim is to bring together contemporary psychological literature on emotion regulation and the classical sentimentalism of David Hume and Adam Smith to arrive at a plausible account of empathy's role in explaining patterns of moral judgment. Along the way, I criticize related arguments by Michael Slote, Jesse Prinz, and others.

Individual and group selection are usually conceived as opposed evolutionary processes. Though cases of synergy are occasionally recognized, the evolutionary importance of synergy is largely ignored. However, synergy is the plausible explanation for the evolution of collectives as higher level individuals i.e., collectives acting as adaptive units, e.g., genomes and colonies of social insects. It rests on the suppression of the predictable tendency of evolutionary units to benefit at the expense of other units or of the wholes they contribute to (...) build. It plausibly explains human cooperation and morality: the molding of human groups into adaptive units. (shrink)

In empirically minded research, it is widely agreed that emotions play an important, even essential, role in moral judgment. Experimental research on moral development, psychopathology, helping behavior, moral judgment, and moral justification has been used to support different new forms of sentimentalism. This article reviews this evidence critically and proposes that although it suggests that emotions play a role in moral judgment, it does so in a more limited way than is often assumed to be the case. Some evidence shows (...) merely that emotions play a role in decision-making, other that emotions are implicated in certain types of moral judgment. What is required, it seems, is a new conceptualization of what is at stake in the rationalism versus sentimentalism debate. (shrink)

An increasingly popular suggestion is that empathy and/or sympathy plays a foundational role in understanding harm norms and being motivated by them. In this paper, I argue these emotions play a rather more moderate role in harms norms than we are often led to believe. Evidence from people with frontal lobe damage suggests that neither empathy, nor sympathy is necessary for the understanding of such norms. Furthermore, people's understanding of why it is wrong to harm varies and is by no (...) means limited to considerations of welfare arising from the abilities to sympathize and/or empathize. And the sorts of considerations of welfare that are central to sympathy and, to some extent empathy, are often already moralized. As such, these considerations cannot form the non-moral foundation of harm norms. Finally, empathy and sympathy are not the only emotions that motivate harm norms. Indeed, much of the evidence that has been adduced in favor of the motivational force of empathy and sympathy are studies on helping, which is quite a different behavior than aggression inhibition. Understanding and being motivated by harm norms are complex abilities. To understand them better, we need to move beyond the current fixation on empathy and sympathy. (shrink)

The term “uncanny valley” goes back to an article of the Japanese roboticist Masahiro Mori. He put forward the hypothesis that humanlike objects like certain kinds of robots elicit emotional responses similar to real humans proportionate to their degree of human likeness. Yet, if a certain degree of similarity is reached emotional responses become all of a sudden very repulsive. The corresponding recess in the supposed function is called the uncanny valley. The present paper wants to propose a philosophical explanation (...) why we feel empathy with inanimate objects in the first place, and why the uncanny valley occurs when these objects become very humanlike. The core of this explanation—which is informed by the recently developing empirical research on the matter—will be a form of empathy involving a kind of imaginative perception. However, as will be shown, imaginative perception fails in cases of very humanlike objects. (shrink)

It is common for philosophers to argue that psychopaths are not morally responsible because they lack some of the essential capacities for morality. In legal terms, they are criminally insane. Typically, however, the insanity defense is not available to psychopaths. The primary reason is that they appear to have the knowledge and understanding required under the M’Naghten Rules. However, it has been argued that what is required for moral and legal responsibility is ‘deep’ moral understanding, something that psychopaths do not (...) have either due to their lacking empathy or practical reason. In the first part of the paper, I argue that psychopaths do not lack the abilities required for deep moral understanding, although they have deficits in those areas. According the M’Naghten Rules, therefore, psychopaths are not insane. Under a less strict formulation of the insanity plea, like the Model Penal Code, however, there is a good case to be made for their lacking substantial capacity. I argue that because psychopathy is an essentially moral disorder, and because of the nature of psychopathic violence, psychopaths should not be excused under the insanity plea. It would be tantamount to excusing someone for committing a crime because they are bad. Arguably, this contravenes the entire system of law. (shrink)

Group selection is one acknowledged mechanism for the evolution of altruism. It is well known that for altruism to spread by natural selection, interactions must be correlated; that is, altruists must tend to associate with one another. But does group selection itself require correlated interactions? Two possible arguments for answering this question affirmatively are explored. The first is a bad argument, for it rests on a product/process confusion. The second is a more subtle argument, whose validity (or otherwise) turns on (...) issues concerning the meaning of multi-level selection and how it should be modelled. A cautious defence of the second argument is offered.

Evolutionary biologists have grappled with the question of the emergenceand maintenance of cooperation since Darwin first listed animal cooperation asapotential problem for his theory of natural selection. Here I review four pathsthat have been delineated in the study of intra-specific cooperation amonganimals.

After reviewing theempirical and theoretical underpinnings of these paths to cooperation, I touchupon some recent work (...) that has attempted to examine (or reexamine) the role ofphylogeny, punishment and morality in the light of cooperative behavior.

The goal of this paper is to defend the theory of generalized evolution (GE) against criticisms by laying down its theoretical principles and their applications in a unified way. Section 2 develops GE theory and its realization in biological evolution (BE) and cultural evolution (CE). The core of GE theory consists of the three Darwinian principles together with the models of population dynamics (PD). Section 3 reconstructs the most important differences between BE and CE. While BE is predominantly based on (...) the replication of genes, CE is based on the reproduction of memes. Memes are understood as the informational “software” of human brains transmitted through social learning processes. The ontology of memes and the concept of cultural fitness is carved out and refined. Finally, section 4 articulates the minimal ontological assumptions of GE theory and the quantitative principles of generalized PD that unify biological PD and evolutionary game theory. (shrink)

The Darwinian theory of evolution is itself evolving and this book presents the details of the core of modern Darwinism and its latest developmental directions. The authors present current scientific work addressing theoretical problems and challenges in four sections, beginning with the concepts of evolution theory, its processes of variation, heredity, selection, adaptation and function, and its patterns of character, species, descent and life. The second part of this book scrutinizes Darwinism in the philosophy of science and its usefulness in (...) understanding ecosystems, whilst the third section deals with its application in disciplines beyond the biological sciences, including evolutionary psychology and evolutionary economics, Darwinian morality and phylolinguistics. The final section addresses anti-Darwinism, the creationist view and issues around teaching evolution in secondary schools. The reader learns how current experimental biology is opening important perspectives on the sources of variation, and thus of the very power of natural selection. This work examines numerous examples of the extension of the principle of natural selection and provides the opportunity to critically reflect on a rich theory, on the methodological rigour that presides in its extensions and exportations, and on the necessity to measure its advantages and also its limits. Scholars interested in modern Darwinism and scientific research, its concepts, research programs and controversies will find this book an excellent read, and those considering how Darwinism might evolve, how it can apply to the human sciences and other disciplines beyond its origins will find it particularly valuable. Originally produced in French (Les Mondes Darwiniens), the scope and usefulness of the book have led to the production of this English text, to reach a wider audience.

In multicellular organisms, cells are frequently programmed to die. This makes good sense: cells that fail to, or are no longer playing important roles are eliminated. From the cell’s perspective, this also makes sense, since somatic cells in multicellular organisms require the cooperation of clonal relatives. In unicellular organisms, however, programmed cell death poses a difficult and unresolved evolutionary problem. The empirical evidence for PCD in diverse microbial taxa has spurred debates about what precisely PCD means in the case of (...) unicellular organisms. In this article, we survey the concepts of PCD in the literature and the selective pressures associated with its evolution. We show that definitions of PCD have been almost entirely mechanistic and fail to separate questions concerning what PCD fundamentally is from questions about the kinds of mechanisms that realize PCD. We conclude that an evolutionary definition is best able to distinguish PCD from closely related phenomena. Specifically, we define “true” PCD as an adaptation for death triggered by abiotic or biotic environmental stresses. True PCD is thus not only an evolutionary product but must also have been a target of selection. Apparent PCD resulting from pleiotropy, genetic drift, or trade-offs is not true PCD. We call this “ersatz PCD.”. (shrink)

Paul Seabright argues that strong reciprocity was crucial in the evolution of large-scale cooperation. He identifies three potential evolutionary explanations for strong reciprocity. Drawing (like Seabright) on experimental economics, I identify and elaborate a fourth explanation for strong reciprocity, which proceeds in terms of partner choice, costly signaling, and competitive altruism.

We describe the results of an experiment testing for the presence of strong altruism among Christians in New Zealand. The study examined anonymous participant generosity to cohort. We found that in modified dictator games, anonymous Christians in New Zealand gave significantly more to Canadian Christians than anonymous New Zealand citizens gave to their fellow citizens. The gifting opportunities occurred after anonymous benefactors observed recipients willingly undertake costly acts of group commitment. We found that mean gifting after witnessing a fellow group (...) member metaphorically "fall on a hand grenade" to punish a member of an out-group was almost four times greater in the Christian group than it was in the New Zealand control. Our data support the hypothesis that religious altruism exists and is especially strong among Christians in New Zealand. The data also weakly support a multi-level selection hypothesis for the evolution of religious altruism. (shrink)

In this article we review the emerging literature on the self-transcendent emotions. We discuss how the self-transcendent emotions differ from other positive emotions and outline the defining features of this category. We then provide an analysis of three specific self-transcendent emotions—compassion, gratitude, and awe—detailing what has been learned about their expressive behavior, physiology, and likely evolutionary origins. We propose that these emotions emerged to help humans solve unique problems related to caretaking, cooperation, and group coordination in social interactions. In our (...) final section we offer predictions about the self-transcendent emotions that can guide future research. (shrink)

Team reasoning gives a simple, coherent, and rational explanation for human cooperative behavior. This paper investigates the robustness of team reasoning as an explanation for cooperative behavior, by assessing its long-run viability. We consider an evolutionary game theoretic model in which the population consists of team reasoners and ‘conventional’ individual reasoners. We find that changes in the ludic environment can affect evolutionary outcomes, and that in many circumstances, team reasoning may thrive, even under conditions that, at first glance, may seem (...) unfavorable. We also pursue several extensions that augment the basic account, and conclude that team reasoning is an evolutionarily viable mechanism with the potential to explain behavior in a range of human interactions.

Science depends on judgments of the bearing of evidence on theory. Scientists must judge whether an observation or the result of an experiment supports, disconfirms, or is simply irrelevant to a given hypothesis. Similarly, scientists may judge that, given all the available evidence, a hypothesis ought to be accepted as correct or nearly so, rejected as false, or neither. Occasionally, these evidential judgments can be made on deductive grounds. If an experimental result strictly contradicts a hypothesis, then the truth of (...) the data deductively entails the falsity of the hypothesis. In the great majority of cases, however, the connection between evidence and hypothesis is non-demonstrative, or inductive. In particular, this is so whenever a general hypothesis is inferred to be correct on the basis of the available data, since the truth of the data will not deductively entail the truth of the hypothesis. It always remains possible that the hypothesis is false even though the data are correct. (shrink)

Group beneficial norms are common in human societies. The persistence of such norms is consistent with evolutionary game theory, but existing models do not provide a plausible explanation for why they are common. We show that when a model of imitation used to derive replicator dynamics in isolated populations is generalized to allow for population structure, group beneficial norms can spread rapidly under plausible conditions. We also show that this mechanism allows recombination of different group beneficial norms arising in..

In this paper, we offer an analysis of ‘group intentions.’ On our proposal, group intentions should be understood as a state of equilibrium among the beliefs of the members of a group. Although the discussion in this paper is non-technical, the equilibrium concept is drawn from the formal theory of interactive epistemology due to Robert Aumann. The goal of this paper is to provide an analysis of group intentions that is informed by important work in economics and formal epistemology.

According to explanatory individualism, every action must be explained in terms of an agent's desire. According to explanatory nonindividualism, we sometimes act on our desires, but it is also possible for us to act on others' desires without acting on desires of our own. While explanatory nonindividualism has guided the thinking of many social scientists, it is considered to be incoherent by most philosophers of mind who insist that actions must be explained ultimately in terms of some desire of the (...) agent. In the first part of the paper, I show that some powerful arguments designed to demonstrate the incoherence of explanatory nonindividualism fail. In the second part of the paper, I offer a nonindividualist explanation of the apparent obviousness of belief-desire psychology. I argue that there are two levels of the intelligibility of our actions. On the more fundamental (explanatory) level, the question "Why did the agent do something?" admits a variety of folk-psychological categories. But there is another (formation-of-self) level, at which the same question admits only of answers that ultimately appeal only to the agent's own desires. Explanatory individualism results from the confusion of the two levels. (shrink)

My aim is to challenge recent attempts at reconciling moral realism and naturalism by pushing ethical naturalists into a dilemma. According to one horn of the dilemma, ethical naturalists must either build unique facts and properties about divergent social structures into their subvenient sets of natural facts and properties, and so jeopardize the objectivity of moral truths, or insist, in the face of all possible worlds in which people have different moral beliefs than ours, that they are all mistaken—this despite (...) the fact that the belief-forming mechanism responsible for their moral beliefs was never concerned with the truth of those beliefs in the first place. This will bring me to suggest that moral properties might only weakly supervene upon natural phenomena. But, according to the other horn of the dilemma, weak supervenience is a defeater for moral knowledge. (shrink)

Humans rely heavily on their prosocial relationships. We propose that the experience and display of prosocial emotions evolved to regulate such relationships through inhibiting individual selfishness in service of others. Two emotions in particular serve to meet two central requirements for upholding prosociality: gratitude motivates maintenance of ongoing prosocial interactions, and guilt motivates repair of ruptured prosocial interactions. We further propose, and review developmental evidence, that nascent forms of these two emotions serve their respective functions from early in ontogeny. The (...) remarkably early emergence of these prosocial emotions allows even very young children to participate in and benefit from prosociality. We discuss the implications of and challenges to this conclusion and identify pressing future directions for this work. (shrink)

A number of recent discussions have argued that George Price's equationfor representing evolutionary change is a powerful and illuminatingtool, especially in the context of debates about multiple levels ofselection. Our paper dissects Price's equation in detail, and comparesit to another statistical tool: the calculation and comparison ofaverage fitnesses. The relations between Price's equation and equationsfor evolutionary change using average fitness are closer than issometimes supposed. The two approaches achieve a similar kind ofstatistical summary of one generation of change, and they (...) achieve thisvia a similar loss of information about the underlying fitnessstructure.

Human beings are highly irrational, at least if we hold to an economic standard of ‘rationality’. Experimental economics studies the irrational behavior of human beings, with the aim of understanding exactly how our behavior deviates from the Homo economicus, as ‘rational man’ has been called. Insofar as philosophical theories depend upon rationality assumptions, experimental economics is the source of both problems and (at least potential) solutions to several philosophical issues. This article offers a programmatic and highly biased survey of some (...) of these issues, with the hope of convincing the reader that experimental economics is well-deserving of careful study by philosophers.

In this paper I argue against the claim, recently put forward by some philosophers of biology and evolutionary biologists, that there can be two or more ontologically distinct levels of selection. I show by comparing the fitness of individuals with that of collectives of individuals in the same environment and over the same period of time – as required to decide if one or more levels of selection is acting in a population – that the selection of collectives is a (...) by-product of selection at the individual level; thus, talking about two or more levels of selection represents merely a different perspective on one and the same process.
